Karen Signell's novel about Smokey Bear has been her life's work. As part of her research, the Boca Raton woman collected 60 photographs of the black bear from when he was rescued from a forest fire in New Mexico to his years as on exhibit at Washington D.C.'s National Zoo. They appear in the pages of her novel, "Smokey Bear: The Cub Who Left His Pawprints on History." See a sampling of those photos here. All were taken in black and white and some were colorized for Signell's e-book.
